Netptune has 8 named moons (4 unnamed) and has large storms with the fastest winds of any planet in the solar system (2000 km/hr.).
The unit of frequency is the hertz (Hz), one cycle per second, named after Heinrich Hertz. For our purposes, we shall use much higher frequencies. One thousand Hz is a kHz (kilohertz); one thousand kHz is a MHz (megahertz); one thousand MHz is a GHz (gigahertz); one thousand GHz is a THz (terahertz).
Hertz is the SI unit for frequency. Frequency is defined as the number of cycles per second. The word cycles refers to a stated number of fully-completed wave transitions of: * a physical sound wave traveling through a solid (like wood or bone or metal), a fluid (like water), a gas (like air), etc. or.
